Cordero Morton
     Minerva Cordero, an associate professor of mathematics and a Distinguished Teaching Professor, is joining the College's administrative team as associate dean for student affairs. She will replace Edward Morton, who is retiring in May after 30 years with UT Arlington.
     Cordero will work with Morton this semester to ensure a smooth transition.
     "Dr. Cordero is an excellent teacher and has substantial administrative experience," Dean Pamela Jansma said. "She has served as associate dean of the Honors College here at UT Arlington and has worked in a variety of other roles with students, and these experiences make her an ideal successor to Ed Morton. Ed's tireless dedication to the College of Science has been instrumental to the success of our students and our programs for three decades. We will miss him and his leadership, but I feel our student programs will be in very good hands with Dr. Cordero."
      Morton has served as the College's pre-med advisor since his arrival in 1983, and has taken on a host of other duties over the years, including pre-med curriculum coordinator; approving the College's degree plans; handling health professions scholarships; directing the Joint Admissions Medical Program (JAMP); and creating and enforcing the College's academic standards, which has resulted in a major increase in the number of students meeting the College's GPA requirements of 2.25.
      In other Dean's staff news, Amy Osborn has been promoted to Executive Assistant to the Dean and Program Coordinator for Technology Initiatives. She will work with the director of the College's Math Emporium as well as assist faculty in implementing new classroom technology as well as working with academic partnerships. Derrick Austin has been promoted to Web Software Developer; he is responsible for the College's web applications as well as maintaining its website.
Basu assumes leadership role in EES; Fuchs steps in as interim chair of Psychology
Basu Fuchs
     The Department of Earth and Environmental Science underwent a change in leadership with the start of the Spring 2013 semester, as Asish Basu took over the chair role from John Wickham.
     Basu came to UT Arlington this month from the University of Rochester, where he had worked since 1978. His research interests are diverse and are primarily based on petrological, mineralogical and geochemical approaches in understanding aspects of Earth's evolution. He uses trace element, radiogenic and stable isotopes as principal tools in these studies, along with other standard laboratory and field observations.
     Basu earned a Ph.D. in Geology from the University of California at Davis in 1975, an M.S. in Geophysical Science from the University of Chicago in 1969, an M.S. in Geology from Calcutta University in 1966 and a B.S. in Geology, Physics and Mathematics from Calcutta University in 1964.
     The Department of Psychology is in a period of leadership transition, and associate professor Perry Fuchs has assumed the role of interim chair until a search committee finds a permanent replacement for Robert Gatchel, who stepped down January 1 after eight years as head of the department. Gatchel is focusing on his role as director of the new Center of Excellence for the Study of Health and Chronic Illnesses.<
Alumnus Krystinik offers advice to grads at College of Science Fall 2012 commencement
Krystinik
     The College of Science officially conferred graduate status to a new group of students during the Fall 2012 Commencement ceremony on December 16 at College Park Center.
     For the first time, the College of Science took part in a joint ceremony along with the School of Architecture. Dean Pamela Jansma introduced the guest speaker for the ceremony, College of Science alumnus Lee Krystinik, who earned a B.S. in Geology in 1977. He went on to earn master's and doctoral degrees from Princeton University and is principal and founder of Fossil Creek Resources in Arlington. He is also president-elect of the American Association of Petroleum Geologists.
     UT Arlington has been an important part of Krystinik's family, as his parents, brother and sister all graduated from the University. He attended classes while also working to pay his expenses, and says he "couldn't have asked for a better education" than what he received at UT Arlington. He encouraged the new graduates to stress communication, to be sincere, to never complain and never explain, to respect everyone they deal with, and to be unafraid to fail.
     "One big thing in life is, when we act on our fears, we're most likely to make them come true," he said.
     Krystinik wished the graduates good luck and urged them to share their knowledge with others.
     "When life presents you with challenges and difficulties, forge ahead," he said. "Do what you believe is right, treat others with respect and, more than anything else, remember to have fun."

Park, Ellinger present research using new 3D approach for simulation of supernovas
Park
     Two UT Arlington researchers want to bridge the gap between what is known about exploding stars and the remnants left behind thousands of years later. So they're trying something new using SNSPH, a complex computer code developed at Los Alamos National Laboratory.
     On January 8, Carola I. Ellinger, a post-doctoral researcher and Sangwook Park, an assistant professor of physics, presented their research on "3D Simulations of Supernovae into the Young Remnant Phase" at the national meeting of the American Astronomical Society in Long Beach, Calif. Their oral presentation focused on first efforts to use SNSPH, a parallel 3-dimensional radiation hydrodynamics code written in 2005, to create 3D simulations of a core-collapse supernova evolving into remnants.
     "There are a lot of numerical simulations for the explosion of the supernova and a lot of simulations of the blast wave expanding into interstellar medium, but there was no useful work connecting the two, even though the physics are connected," Park said. "Now, we are using the most appropriate program we know to do that."

Musielak receives $301K grant from NSF to study magnetic plasma waves in the Sun
Black
Musielak
     Zdzislaw Musielak, professor of physics, has been awarded a three-year, $301,339 National Science Foundation grant to investigate Alfvén waves in the Sun, a phenomenon vital to understanding Earth's nearest star.
     "The Sun is the source of energy that sustains all life on Earth, but there is much that remains unknown about it," said Musielak, a two-time winner of the international Humboldt Prize for his research into the sun and solar-type stars. "With this research, we hope to explore one of the great mysteries what forces fuel the heat of the Sun's outer atmosphere and the basic physical processes for creating its magnetic influence on Earth and other planets."
     Alfvén waves are magnetic plasma waves named after Hannes Alfvén, who received a Nobel Prize in 1970 for their prediction. Their existence helps explain why the sun's corona, or upper atmosphere, is hotter than the solar surface. Understanding Alfvén waves is also crucial to explaining the speed of solar winds, a stream of highly-charge particles released into space by the Sun.

Researchers say Amazon deforestation raises fears about loss of microbial diversity
Rodrigues
     Research from an international team of microbiologists, including UT Arlington assistant professor of biology Jorge Rodrigues, has revealed a new concern about deforestation in the Amazon rainforest a troubling net loss in the diversity among the microbial organisms responsible for a functioning ecosystem.
     The group, which also includes professors from the University of Oregon, University of Massachusetts, Michigan State University and University of Sao Paulo, sampled a 100 square kilometer area, about 38 square miles, in the Fazenda Nova Vida site in Rondônia, Brazil, a location where rainforest has been converted to agricultural use. Their findings in part validated previous research showing that bacteria in the soil became more diverse over the years, as it was converted to pasture.
     But their findings contradicted prior thinking by showing that the loss of restricted ranges for different kinds of bacteria communities resulted in a biotic homogenization and net loss of diversity overall. Scientists worry that the loss of genetic variation in bacteria across a converted forest could reduce ecosystem resilience.

Dasgupta's research yields more effective technique to analyze ions in solution
Dasgupta
     Purnendu 'Sandy' Dasgupta's work to develop a more efficient, effective way of measuring ions in solution has led to a new device in the scientific marketplace that could improve water quality testing and manufacturing methods.
     Dasgupta, a professor of chemistry and biochemistry, invented the charge detector for ion chromatography, along with Bingcheng Yang, a member of his research group, and Kannan Srinivasan, technical director for Thermo Fisher Scientific Inc. The U.S. Patent office recently assigned a patent for the new technology to the UT System Board of Regents and Dionex Corporation, which is based in Sunnyvale, Calif. Thermo Fisher is Dionex's parent company.
     "The fact that ions carry a charge has been known since before the 20th Century began. For the first time, we can now measure that charge in a solution," said Dasgupta, the Jenkins Garrett Professor of Chemistry and Biochemistry. "This gives you a possibility that didn't exist before. It gives you new information that couldn't be accessed before."

Rodrigues, team study predator-producing bacteriophages found in mammal intestines
Rodrigues
     Unique viruses called bacteriophages may play an important role in competition among bacterial strains, influencing the overall ecosystem of the human intestine, scientists at UT Arlington and UT Southwestern Medical Center say.
     A team led by Lora V. Hooper, an associate professor of immunology and microbiology at UT Southwestern Medical Center, and including UT Arlington assistant professor of biology Jorge Rodrigues examined the bacteriophages, or phages, produced by genetic information harbored in the chromosome of the mammalian gut bacterium Enterococcus faecalis. They found that a phage unique to Enterococcus faecalis strain V583 in mice acts as a predator, infecting and harming other similar, competing bacterial strains. They believe these lab results suggest what goes on in the human intestine.
     "This organism is using phage as a way to compete in your gut. If the phage is released and gets rid of all the other microbes, then strain V583 will have more nutrients available," Rodrigues said. "It opens up new questions about the role of phages in the gut system. Ultimately, you could use this as a technique to control bacteria in a natural way."

Melotto co-authors paper helping to unlock the secrets of plant defense mechanisms
Melloto
     Researchers examining how the hormone jasmonate works to protect plants and promote their growth have revealed how a transcriptional repressor of the jasmonate signaling pathway makes its way into the nucleus of the plant cell.
     They hope the recently published discovery will eventually help farmers experience better crop yields with less use of potentially harmful chemicals.
     "This is a small piece of a bigger picture, but it is a very important piece," said Maeli Melotto, assistant professor of biology.
     Melotto recently co-authored a paper that advances current understanding of plant defense mechanisms with her collaborator Sheng Yang He and his team at Michigan State University's Department of Energy Plant Research Laboratory (DOE-PRL). He is a Howard Hughes Medical Institute-Gordon and Betty Moore Foundation investigator. A paper on the collaboration was published online Nov. 19 in the Proceedings of the National Academy of Sciences under the title, "Transcription factor-dependent nuclear import of transcriptional repressor in jasmonate hormone signaling."

Mohanty's team creates fiber-optic wrench that can rotate, move microscopic particles
Mohanty
     UT Arlington physicists have developed a new fiber-optic spanner, or wrench, that uses two laser beams to stably rotate and move microscopic objects, such as living cells, an innovation that will help scientists to work more efficiently at the microscopic level.
     The new technology surpasses current methods of fiber-optic rotation because it allows the object to be rotated at any axis, giving a fuller view. Through this method, cancer cells could be imaged during rotation or oocyte cells could be moved during in vitro fertilization, researchers said. The spanner also can use a "rotating bead handle" to twist and untwist DNA molecules to allow its sequencing more rapidly than current methods.
     The innovation is detailed in a new report, "Fiber-optic Spanner," published in the journal Optics Letters and available online here. Samarendra Mohanty, assistant professor of physics, led the research team and co-authored the paper with doctoral student Bryan Black.
